Effect of Various Parameters on Hydrograph and Rainfall Runoff Relationship Establishment by using Armfield S10 Rainfall Hydrograph

Rainfall-runoff process of a watershed is important for water resources planning, flood forecasting, design flood estimation through rainfall runoff process, and many other applications. For a mathematical simulation of this phenomenon, controlled set of experiments were conducted to investigate this process through experimentation on the catchment system placed over a rainfall simulator to obtain runoff hydrograph data. The experiments were carried out over an impermeable plane surface (smooth metal sheet), with a uniform rectangular cross section of dimension one meter wide and two meter long. Laboratory experiments were conducted to know behavior of this phenomenon using rainfall simulator. In this project, stream flow from a single storm, stream flow from multiple storms, stream flows with reservoir storage experiments are performed. Result and conclusion are found out on the basis of experiments performed.
